To all whom 'it may conce/m: i

Be it known that I, HENRY L. Garmin, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and llmproved Engine Control, of which the following is a full, clear, and exact description.

My invention relates to means for controlling internal-combustionv engines, and it has reference more particularly to means for simultaneously controlling the ignition and the fuel. supply of an internal-combustion engine.

An object of the invention is to rovide a simple and inexpensive control w 'ich can be applied to an internal-combustion engine having a car ureter and timer.

Another object of the invention is to provide a control of the class described in gine provided with a control embodying anyv invention;

Fig. 2 is a longitudinal sectionthrough the needle valve of a carburetor which is to be operated in unison with the timer of the engine; and

Fig. 3 is a diagrammatic view showing that the advance of ignition causes a decrease of fuel supply opening.,

Referring to the drawin s, 4 is the spark lever which is connected y :a rod 5 to a crank 6 mounted to participate in the movenient of the lever. Illhe crank is connected by a rod 'i' to the timer 8.

The carbureter 9 of the engine lhas the needle valve 10 thereof threaded in a sleeve il which is in turn threaded into the body l2 of the carburetor. The sleeve has an arm. 13 which may be connected to the rod 5 to be op erated when the timer is operated, or it4 may be connected, as shown in the drawings, by a rod lato a bell-crank lever 15 which is connected in turn by a link 16 to the timer 8. lt will be seen that the. connection between the needle valve and the timer is such that an "advance in sparking will cause the drawin s,

the engine. inversely, a retard in sparbng Will increase the 4,openingwhi'ch supplies fuel to the engine. i While I have described the principle of.,` operation, together with the device which lf: now consider to be the best 'embodiment thereof, I desire to have it understood that, the device shown is merely illustrative and that such changes may be made as are Witht.` in the scope of the appended claims. j

lf claim: t??

1. An engine control of the class described comprising incombination a carbureterda spark control, and means connecting the spark control to the carburetor to increase the fuel supply Without varyin the air supply when the spark is retar ed, and vice versa. j.' 4

2. An engine control of the class descrijb comprising in combination a spark control, a carburetor having a needle valve, and means connecting the needle valve to the spark control to reduce the fuel supply as distinguished from fuel mixture supply when the spark is advanced and increase the fuel supply opening when the spark is retarded.

3. An engine control of the class described comprising in combination a carburetor having a needle valve, a timer for regulating the spark of the engine, and means for operating the timer and the needle valve simultaneously so that an advance in sparking, causes a reduction of fuel supply opening, and vice versa.

li. An engine control of the class described comprising in combination a carburetor hav ing a needle valve, a timer for controlling the spark of the engine, and means connect ing the needle valve tothe timer so that advance of sparking causes a closing of the valve, and vice versa.

5. An engine control of the class described comprising in combination a carburetor hav- Patented @fully it', fdilfhj needle valve 10 toI descend with the sleeve and reduce the opening supplying fuelfto ing a needle valve, a sleeve threaded into the carburetor and in threaded engagement with the needle valve, a timer, means for operating the timer, and means connecting the timer to the sleeve so that an advance in spark causes a closing of the needle valve, and vice versa.
